Xu Kuohai f6606a44bc bpf, arm64: Emit BTI for indirect jump target ... On CPUs that support BTI, the indirect jump selftest triggers a kernel panic because there is no BTI instructions at the indirect jump targets. Fix it by emitting a BTI instruction for each indirect jump target. For reference, below is a sample panic log. Internal error: Oops - BTI: 0000000036000003 [#1] SMP ...
